HANXER Spa Filter Cartridge Replacement 2-Pack — 50-Micron Trilobal, 1 1/2" SAE Screw-In, 8¼" x 6"

HANXER Spa Filter Cartridge is a 2-pack replacement filter designed to match Unicel 6CH-940 and compatible models, offering trilobal 50-micron filtration in an 8 1/4" x 6" screw-in cartridge for clearer spa and hot tub water.

This pair of HANXER replacement cartridges is built to fit many popular hot tub and spa systems that use a 1 1/2" SAE screw-in connection. Each cartridge uses a trilobal polyester media with a reinforced frame and end caps, giving a larger capture area and improved durability compared with standard pleated filters. The set is IAPMO-tested to NSF safety standards and is free of BPA and unwanted residues.

Which original filter models does this replace?

These HANXER cartridges are compatible with a wide range of OEM part numbers, making them a straightforward swap for many spa owners. Double-check your original filter measurements and thread type before ordering to ensure proper fit.

• Compatible with Unicel 6CH-940, PWW50P3, 817-0050
• Works with Filbur FC-0359, 25252, 03FIL1400
• Also fits Aladdin 14510, Baleen AK-9019, 60401 and similar models

How does the trilobal 50-micron media improve water clarity?

The trilobal fiber structure increases surface area and adsorption compared with conventional fibers, so it traps fine particles more effectively. At 50 microns, it captures hair, sediment, sand and small organic debris while maintaining good water flow and pump efficiency.

• Three-leaf fiber design multiplies adsorption surface
• 50-micron layer captures fine dust and small debris
• Maintains balanced flow to protect pumps and heaters

What construction features affect durability and maintenance?

HANXER cartridges pair thickened polyester media with reinforced end caps, high-strength adhesive tape and a sturdy internal support frame. These elements reduce the risk of collapse and tearing during regular cleaning, extending usable life when cared for properly.

• Reinforced anti-breakage end caps resist cracking
• Robust internal support frame prevents deformation
• Recommended regular rinsing; do not backwash (may damage element)

Is this safe for long-term contact with spa water?

HANXER filters are tested by IAPMO to meet NSF safety benchmarks for materials in contact with pool and spa water. Components are manufactured to avoid leaching or odors so the filter won’t introduce unwanted substances into your water.

• IAPMO-tested and NSF-aligned component verification
• BPA-free, odorless construction with no residue
• Designed for repeated rinsing and standard spa care routines

Who this is for: These HANXER 2-pack cartridges suit spa and hot tub owners who need a reliable, direct-replacement filter for common OEM numbers and want improved particulate capture without sacrificing flow. Ideal if you prefer filters with reinforced build quality, easier cleaning, and NSF-tested materials. Before buying, confirm your filter's length (8 1/4"), outside diameter (6"), and 1 1/2" SAE screw-in bottom thread match your system.
